The polymeric structure of the title complex, [Cu(C7H4ClO3)2(C6H7NO)2] n , at 100 (2) K contains two-dimensional sheets parallel to the ac plane. The CuII atom, lying on an inversion centre, has an octahedral coordination environment. It is bonded in a trans-square-planar arrangement to the N atoms of two 3-pyridylmethanol molecules and one carboxylate O atom from each of two 4-chlorosalicylate anions. The axial positions are also occupied by 3-pyridylmethanol, but coordinated through O rather than the pyridyl N atom.

In the title complex, [Zn(C10H10N4)3](NO3)2, the six-coordinate ZnII atom lies at the intersection of three twofold axes in a slightly disorted octahedral coordination environment. The N atom of a nitrate anion is located on a threefold axis. In the crystal structure, intermolecular N—H...N and N—H...O hydrogen bonds between cations and anions form a two-dimensional network perpendicular to the c axis.

The binuclear title complex, di-μ-iodido-bis({2-[(benzylamino-κN)methyl]phenyl-κC1}palladium(II)), [Pd2I2(C14H14N)2], was prepared by reaction of [Pd{C6H4(CH2NHCH2Ph)-2}(μ-OAc)]2with NaI. It crystallizes with one discrete molecule in the asymmetric unit. The molecule presents an iodide-bridged dimeric structure with acisoidarrangement with respect to theC,N-cyclopalladated ligands. Both PdIIatoms have a slightly distorted square-planar coordination environment. Weak intermolecular contacts of the type C—H...Pd seem to have a significant influence on the arrangement of the molecules along thebaxis in the crystal.

The title complex, [Rh(C20H15N2OS)(C8H12)], exhibits an essentially square-planar coordination environment around the RhIatom, which bears a bidentate cyclooctadiene ligand as well as a monoanionic bidentate benzoylthioureate ligand. The RhIatom, the S- and O-donor atoms and the alkene centroids of the cyclooctadiene ligand do not deviate by more than 0.031 Å from their least mean-squares plane.

In the centrosymmetric binuclear title complex, [Cu2(C7H4IO2)4(H2O)2], the two CuIIions [Cu...Cu = 2.6009 (5) Å] are bridged by four 2-iodobenzoate (IB) ligands. The four nearest O atoms around each CuIIion form a distorted square-planar arrangement, the distorted square-pyramidal coordination being completed by the O atom of the water molecule at a distance of 2.1525 (16) Å. The dihedral angle between the benzene ring and the carboxylate group is 25.67 (13)° in one of the independent IB ligands and 6.44 (11)° in the other. The benzene rings of the two independent IB ligands are oriented at a dihedral angle of 86.61 (7)°. In the crystal, O—H...O interactions link the molecules into a two-dimensional network. π–π contacts between the benzene rings [centroid–centroid distances = 3.810 (2) and 3.838 (2) Å] may further stabilize the structure.

In the title complex, [Pd(N3)2(C10H9N3)], the PdIIion is in a slightly distorted square-planar coordination environment. The ligator atoms comprise the two pyridine N atoms of the chelating di-2-pyridylamine (dpa) ligand and two N atoms from two azide anions. The dpa ligand coordinates the Pd atom in a boat conformation, the dihedral angle between the pyridine rings being 24.4 (1)°. The pyridine rings are somewhat inclined to the least-squares plane of the PdN4unit, making dihedral angles of 29.02 (9) and 26.47 (9)°. The azide ligands are slightly bent, with N—N—N angles of 173.0 (4) and 174.2 (4)°. In the crystal, molecules are connected by N—H...N and C—H...N hydrogen bonds, forming chains along thecaxis. When viewed down thebaxis, successive chains are stacked in opposite directions. Intramolecular C—H...N hydrogen bonds are also observed.

In the title polymeric complex, {[FePt(CN)4(H2O)2]·2C3H6O} n , the FeII cation has an octahedral [FeN4O2] geometry being coordinated by two water molecules and four cyanide anions. The Pt cation is located on an inversion centre and has a square-planar coordination environment formed by four cyanide groups. The tetracyanoplatinate anions bridge the FeII cations to form infinite two-dimensional layers that propagate in the bc plane. Two guest molecules of acetone per FeII are located between the layers. These guest acetone molecules interact with the coordinated water molecules by O—H...O hydrogen bonds.

The core of the title complex, bis[hexaaquahemiaquapentakis(μ3-glycinehydroxamato)sulfatopentacopper(II)terbium(III)] sulfate hexahydrate, [TbCu5(SO4)(GlyHA)5(H2O)6.5]2(SO4)·6H2O (1), which belongs to the 15-metallacrown-5 family, consists of five glycinehydroxamate dianions (GlyHA2−; C2H4N2O2) and five copper(II) ions linked together forming a metallamacrocyclic moiety. The terbium(III) ion is connected to the centre of the metallamacrocycle through five hydroxamate oxygen atoms. The coordination environment of the Tb3+ ion is completed to an octacoordination level by oxygen atoms of a bidentate sulfate and an apically coordinated water molecule, while the copper(II) atoms are square-planar, penta- or hexacoordinate due to the apical coordination of water molecules. Continuous shape calculations indicate that the coordination polyhedron of the Tb3+ ion in 1 is best described as square antiprismatic. The positive charge of each pair of [TbCu5(GlyHA)5(H2O)6.5(SO4)]2 2+ fragments is compensated by a non-coordinated sulfate anion, which is located on an inversion center with 1:1 disordered oxygen atoms. Complex 1 is isomorphous with the previously reported compounds [LnCu5(GlyHA)5(SO4)(H2O)6.5]2(SO4), where Ln III = Pr, Nd, Sm, Eu, Gd, Dy and Ho.

The molecular structure of the title complex, [Ni(C13H8F2N2O)(C14H32P2)] or Ni(oFPU)(dippe), where oFPU is the dianion of bis(2-fluorophenyl)urea and dippe is 1,2-bis(di-isopropylphosphino)ethane, comprises an NiII atom with a distorted square-planar coordination environment (geometry index τ4 = 0.195). One of the fluorophenyl rings of the oFPU ligand is disordered over two sets of sites in an 0.832 (7):0.168 (7) ratio. The crystal structure displays C—H...O and C—H...F hydrogen-bonding interactions, leading to chains with R 2 2(12) motifs extending parallel to [100]. The title compound might be of interest with respect to the production of urea and carbamate derivatives of nickel(II).

The PtII atom in the title complex, [Pt(C15H18N4O4S)(C2H6OS)], exists within a square-planar NS2O donor set provided by the N, S, O atoms of the di-anionic tridentate thiosemicarbazo ligand and a dimethyl sulfoxide S atom. The two chelate rings are coplanar, subtending a dihedral angle of 1.51 (7)°. The maximum deviation from an ideal square-planar geometry is seen in the five-membered chelate ring with an S—Pt—S bite angle of 96.45 (2)°. In the crystal, molecules are linked via N—H...O, C—H...O, C—H...N and C—H...π interactions into two-dimensional networks lying parallel to the ab plane. The conformations of related cyclohexylhydrazine-1-carbothioamide ligands are compared to that of the title compound.

In the CuIIcompoundcatena-poly[[copper(II)-μ-[2-({2-[2-(naphthalen-2-yloxy)-1-oxidoethylidene]hydrazin-1-ylidene}methyl)phenolato]] dimethylformamide monosolvate monohydrate], {[Cu(C19H14N2O3)]·C3H7NO·H2O}n, (I), the CuIIcation isO,N,O′-chelated by one ligand and furtherN,O-chelated by a second ligand, and exhibits a distorted square-pyramidal coordination environment. The ligand acts as an overall pentadentate bridge between two metal ions, thus forming a novel coordination polymer. In the trinuclear NiIIcompound diaquabis(1H-imidazole)bis[μ-2-oxido-N′-(1-oxido-2-phenoxyethylidene)benzohydrazidato]trinickel(II) dimethylformamide tetrasolvate, [Ni3(C15H11N2O4)2(C3H4N2)2(H2O)2]·4C3H7NO, (II), the three NiIIcations are directly linked by twotransdiazine (N—N) bridges and are strictly collinear by symmetry. The central NiIIcation, located on an inversion centre, is coordinated by two water O atoms and is furtherN,O-chelated by two 2-oxido-N′-(1-oxido-2-phenoxyethylidene)benzohydrazidate(3−) ligands in an elongated octahedral coordination geometry. The two terminal centrosymmetrically related NiIIcations are coordinated by an imidazole ligand andO,N,O′-chelated by a hydrazidate ligand in a distorted square-planar coordination geometry. Hydrogen bonds link individual molecules of (II) into a chain along [100].
